Sock Systems are relatively easy. A specialized trencher digs and installs fabric wrapped perforated pipe under the construction area. The drain length is determined by the soil conditions and the water table. In general, drain lengths of 200 to 400 feet and installation depths of up to 18 feet are common. Multiple runs in parallel can be used. Individual runs are collected in a common header for connection to a wellpoint pump. Usually after 2 to 3 days the water table has been lowered enough for initial excavation to begin. After subsurface construction is completed, pumps and header can be removed from the system allowing the water table to return to normal. Sock underdrain is capped for future use or abandoned in place.
